Monatti Gallery is home to the collection of offices of art dealer Antonio Monatti.
When Antonio "discovers" Chris Griffin's talent after seeing a picture he gave Peter in the back of their car in "A Picture's Worth a Thousand Bucks", he talks Chris and the family into coming to New York City. After giving Chris a makeover, he convinces him to dump his family. But at the premier of his show at the gallery, his homage to his father is derided by the art critics, resulting in Antonio throwing him and the other Griffins out.
